Cadillac ATS Real Gas Mileage: Cons
YearComment
On paper, the ATS's engines meet or exceed competitors. Even the base 2.5-liter four-cylinder engine peaks at over 200 horsepower, while the 2.0-liter turbo kicks out 272 and the 3.6-liter V6 321. I found the base engine more satisfactory than most reviewers have. But the other two don't feel as strong as their power ratings suggest they ought to, and could also sound and feel more sophisticated and thrilling. They're all fairly good engines, but none of them is a great engine. Fuel economy falls short of the BMW. The 2.0T engine is EPA-rated 19 city, 30 highway with a manual transmission, 21/31 with an automatic. Step up to the V6, and the numbers fall to 18/28. Deduct a couple of highway mpg with AWD. The BMW's ratings are much higher. The 328i's 2.0T engine is rated 22/34 with a manual transmission, 23/33 with a six-speed automatic. The 335i's six-cylinder engine when paired with an eight-speed automatic transmission somehow manages the same EPA rating as the 328i's four-cylinder. In the real world it doesn't fare as well, though. The V6 in the Infiniti in conjunction with a seven-speed automatic transmission is about even with that in the Cadillac, 19/27. Pair it with a manual transmission and the numbers fall to 18/25, worst of the bunch. see full Cadillac ATS review

Coming from a Trailblazer, we like the average of 21-22 MPG in mixed driving, as were used to about 17 MPG. Fuel economy climbs toward the rated 26 MPG the more highway driving we do. see full Mercury Mariner review

For some reason when new Michelin All Terrain tires with Nitrogen air replaced the Champions from the factory, it plummeted to 17 & 20 mpg. No explanation from Michelin, Costco or Ford/Mercury - they have no idea why. see full Mercury Mariner review
